Turn off the meter. Remove one Philips head screw and lift off the rear battery cover. Replace the 9V battery. Secure the rear battery cover. 3 MO290 V3.0 03/09 Operation Powering the meter 1. 2. 3. Remove the RH sensor protective cap before use. Press the power If the button to turn the meter on. symbol appears or the meter does not turn on, replace the battery. Humidity (Dew point, GPP, g/kg) Measurements 1. 2. 3. 4. 5. 6. Press the power button to turn the meter on. Press the RH button Relative Humidity will be displayed in the primary display and the temperature will be displayed in the secondary display. Press the up or down arrow button to change the temperature units. Press the MODE button to display the DEW point. Press the MODE button to display GPP (°F) or g/kg (°C) Pinless Moisture Measurements 1. 2. 3. Press the power button to turn the meter on. Press the MOIST button to select Moisture measurement.” MOIST”, and “INT” (internal pinless sensor) will appear in the display. Hold the meter so that the rear sensor is away from any surface or your hand. The reading should be near 0.0. If not, press and hold the ZERO button for more than 2 second and the ZERO icon appears. Place the rear sensor on the surface of the material to be tested and read the relative moisture content. 4. Pin Type Moisture Measurements 1. 2. 3. 4. Connect the external pin probe to the jack on the bottom of the meter. Press the power button to turn the meter on. Press the MOIST button twice to select Moisture measurement.” MOIST”, and “EXT” (external pin probe) will appear in the display. Press the probe pins into the material and read the % moisture content in the display. 4 MO290 V3.0 03/09 Infrared Temperature Measurements 1. 2. 3. 4. 5. Press the power button to turn the meter on. Press the IRT button to enable the IR thermometer and the laser pointer. The laser pointer icon will flash while the mode is active. Press the up or down arrow button to change the temperature units Aim the laser pointer at the surface to be measured and read the surface temperature in the secondary display. Release the IRT button. The last temperature measured and the laser icon will remain on the display for approximately 10 seconds before returning to ambient temperature measurement. IRT MAX MIN display: The meter can be set to display only the maximum or minimum temperature measured during an IR scan. 1. 2. With the meter in the IR hold mode, press the MODE button. “MIN” will appear in the display. Press the IRT button to enable the IR thermometer. The meter will display the minimum temperature measured and will update only when a lower temperature is measured. Press the MODE button twice to enable the MAX mode and proceed as stated above for the maximum temperature. The MAX or MIN temperature is not stored when the function is exited. 3. 4. IR Field of View Ensure that the desired target is larger than the spot size. As the distance from an object increases, the spot size of the area measured by the meter becomes larger. The meter’s field of view ratio is 8:1, meaning that if the meter is 8 inches (cm) from the target, the diameter (spot) of the object under test must be at least 1 inch (cm). Refer below to the field of view diagram. 2” @ 16” 1” @ 8” 20mm @ 160mm 40mm @ 320mm WARNING: Do not directly view or direct the laser pointer at an eye. Low power visible lasers do not normally present a hazard, but may present some potential for hazard if viewed directly for extended periods of time. 5 MO290 V3.0 03/09 Condensation Mode The Condensation feature alerts the used when the surface temperature as measured by the IR thermometer is close to or has reached the Dew Point temperature. 1. 2. 3. button to turn the meter on. Press the power Simultaneously press the MOIST/REL and RH buttons. The “COND” icon will appear. Point the meter at a surface, press the IRT button to measure the surface temperature. The small display will indicate the IR surface temperature and the large display will indicate the difference between the IR temperature and the Dew Point temperature. The meter will then report the potential for condensation on that surface in the following manner • If the temperature of the IRT is more than 14°C (25°F) above the Dew Point, the temperature difference shall be displayed, with no other warning. • If the temperature of the IRT is 3-14°C (5-25°F) above the Dew Point, the temperature difference shall be displayed, along with a standard Condensation Indicator icon. The meter shall beep once to confirm that the reading is in the risk area. • If the temperature of the IRT is less than 3°C (5°F) above the Dew Point, the temperature difference shall be displayed, along with a flashing Condensation Indicator icon. The meter shall beep twice to confirm that the reading is in the highrisk area. Press the RH button to exit the mode. 4. 5. Vapor Pressure Mode 1. 2. With the Condensation mode active, press the MODE button to display the Vapor Pressure in mBAR (°F) or kPa (°C). Press the MODE button to exit the Vapor Pressure mode.
